SIMPLE OBSERVATION
- General state of child, colour, hydration, nutrition, activity, posture and movements
- His reaction to environment, interaction with strangers and relationship with parents
- Skin rash – roseola infantum, common childhood infections like measles, rubella, chickenpox
- Viral infections: EBV, EV (Coxsackie, ECHO)
- Bacterial infection, typhoid, pupuric rash of meningococcal and pseudomonas septicaemia, scarlet fever, erythema marginatum
- Reactions to drugs
- Autoimmune disease
Facies: to compared paleness of pt's face: can put your hand by her face to compare
Central cyanosis: if hand is warm, you don't need to look at tongue
Jaundice: look at eyes in natural light, Fluorescent light no good
Rash: occurs everywhere in body. If occurs from head to toe, likely to be infectious (eg. Measles, German measles) - ask about distribution of rash. Where it began, how did it spread
- Eg. Measles: start in face, red eyes, cough, cracked lips, fever for 3-4d, rash and fever continues
- Eg. Roseola infantum: HSV6 - fever for 2-3d, fever comes down, body comes out in generalised rash, starts all over (not like infectious-type rash)
- Eg. erythema infectiosum ("slapped cheek disease"), two red cheeks, fever, sometimes have rash over trunk
- Eg. Parvovirus infection
- Eg. Chickenpox: vesicular eruptions, starts in mouth, always look at mouth, infectious for 1-2d before vesicles erupt, spreads via respiratory droplets (coughing)
- Eg. Atopic dermatitis: red scaly skin around face and flexural areas, thickened on dorsum of foot
Other observations
- Eg. Kawasaki disease: cracked oedematous lips, strawberry tongue, fever for 5-7d, red swollen hands and fingers and feet, rash, peeling of skin on recovery; autoimmune disease related to infection
- Eg. Cavernous haemangioma: small then increases in size in first 6m of life, can obstruct vision, can respond to high-dose steroids orally
- Eg. Heart failure due to haemangioma inside abdomen: retraction of rib cage, resp problems, abdomen distended, umbilicus everted, scrotum oedematous
- Haemangioma - AV malformations, shunting, leading to heart failure
- Eg. Capillary haemagioma - port-wine stain assoc. with similar haemangioma inside meninges. Pt's quite often have epilepsy
HEAD SHAPE
- Oxycephaly: top of head pointed or conical owing to premature closure of coronal and lambdoid sutures (aka acrocephaly, hypsicephaly, turricephaly, steeple head or skull, tower head or skull)
- Bradycephaly
: "slow" head?
- Microcephaly
: abnormal smallness of the head, usually assoc. with MR
- Scaphocephaly
: skull is abnormally long and narrow, as a result of premature closure of the sagittal suture, with heavy centres of ossification in the line of the suture; usually accompanied by inflammation and atrophy of the optic papillae and by MR
- Hydrocephaly
: developmental obstruction of the CSF pathways resulting in marked dilatation of the cerebral ventricles. Fluid is usually under increased pressure. Characterised by enlargement of the head, prominence of the forehead, brain atrophy, mental deterioration and convulsions
- Megalencephaly
: abnormally large brain
- Plagiocephaly
: an asymmetric and twisted condition of the head, resulting from irregular closure of the cranial sutures
- Hydranencephaly
: complete or almost complete absence of the cerebral hemispheres, the space they usually occupy being filled with CSF
Fontanelle close by 18m, tension, posterior fontanelle size
Whenever you see abnormal head shape, check underlying sutures
- Eg. Syndactyl and premature cranial stenosis
- Eg. Oxycephaly: box-shaped head
- Compare cranial vault relative to size of face (use face as comparison)
- Eg. Cystic hydroma: lymph collection, congenital abnormality, operable
- Eg. Lymphangiectasia: like haemangioma. If on hand, there will be something elsewhere - probably in gut (haemangioma: elsewhere in gut and brain)
MEASUREMENTS
B = distance between inner points of eyes
A = between outer points of eyes
C = between pupils
- Chinese: often have broad nasal bridge, can cause pseudosquint (B and C normal, A decreased)
- Inflammation around eye area dangerous (ethmoid, paranasal) - periorbital cellulitis must be treated with ABX (not just topical)
- Storage disorder: cloudy cornea, coarse facial features, bushy eyebrows
- Syndactyl: webbed fingers
- If you have 3 or more minor malformations, you have a 90% chance of having major abnormality (urinary tract, heart)
SYNDROMRAL DISODERS
- Down's syndrome (leukaemia)
- Trisomy 18: dismorphic facies, feet, hands, feet like bottom of rockingchair, fingers overlap
- Turner's syndrome: increased carrying angle, webbed necks (50% of children with Turner's syndrome do not have symptoms and signs; usually just a bit small) - deletion of one of the X-chromosomes
- Prader-Willis syndrome: chromosome 15 deleted, micropenis, obese, MR, spindly fingers on small hands
- Noonan syndrome: male equiv. of Turner's syndrome, somatic features of Turner's syndrome, normal chromosomes, neck webbing, increased carrying angle, low-set hairline; deletion of PTPN11
- Hypochrondroplasia: big head, short limbs, milder form of achondroplasia
- Beak nose: Rubenstein-? Syndrome, broad fingers
- Spondyloepiphyseal dysplasia: skeletal dysplasia affecting spine: short trunk, short stature, mature face, shortening of proximal part
- Amniotic fluid bands: fibrous bands in amniotic fluid sever the limbs of the foetus
